Wideband Air Fuel Ratio (AFR) Sensor Module with Bosch LSU4.9 Sensor

PLX Generation 4 with Bosch Wideband sensor LSU 4.9

Supplier :PLX Devices

Part Number :SMAFRG4

Barcode :897346002726

Availability :In Stock

We're proud to introduce our next generation wideband oxygen sensor controller with intelligent health monitoring technology and current for improved sensor performance. Our new Gen4 Wideband AFR utilizes the next generation in Bosch Wideband Air/Fuel Ratio sensor technology. The Gen4 is faster, more accurate, more durable, and uses less power than the Gen3. The Gen4 also employs the innovative PLX Devices new intelligent health monitoring technology where the oxygen sensor is meticulously monitored every 2mS (488 times per second) to obtain peak performance, accuracy and reaction time. Pair the SM/AFR with the updated patented DM-6 touch screen MultiGauge, battery voltage is displayed from 9V-20V, sensor life is displayed from 0-100%. The oxygen sensor reaction time is displayed from 10mS/1000mS on the brilliant high contrast OLED display.No warranty for the Lambda Sensor in case of wrong installation**

product details

The PLX Wideband AFR (UEGO) combines an accurate, fast response wideband AFR (Air Fuel Ratio) controller with a Bosch LSU4.9 wideband oxygen sensor. The wideband controller (SM-AFR) works with gasoline, bio diesel, ethanol, methanol, E85, LPG, and CNG. It includes two analog outputs (wideband 0-5V, and narrowband 0-1V) for interfacing with 3rd party devices and one digital serial output for interfacing with the DM-6 gauge and other Multi Gauges. The wideband analog output is ideal for interfacing with aftermarket ECU's and data loggers. The narrowband output is ideal for stock narrowband oxygen sensor replacement where the simulated narrowband analog output is fed back into your ECU to make it operate as if the stock narrowband oxygen sensor is still installed while running the PLX wideband setup. All three outputs can be used simultaneously. Additional features include advanced soft start technology which prolongs the oxygen sensor's life and an plastic enclosure for durability and reliability.

iMFD Stands for intelligent multi-functional display. It is the PLX standard for connecting everything in a daisy-chain.

Any product labeled with are fully compatible with each other.

Simple Setup

The simple setup connects to just one SM module. This is great for stand alone gauges.Looking at the above diagram.

PLX Display Modules are also compatible with the PLX iMFD serial stream.

Data Logging

Two Options for datalogging are available. iMFD Data Logger and the iMFD Serial USB Adapter.

Caution!

The sensor is not covered by a warranty in the event of a faulty installation. Please try the sensor before you install it. In case you found that the sensor does not work properly please contacy us as soon as possible.

Correct installation of Lambda sensor.In order to make the sensor last longer you should know the followings :

The sensor should never be installed the sensor on the exhaust without power supply in case the engine is running.

The ideal distance of sensor installation from the downstream is just before the catalyst.

If the installation position is no more 50cm from the downstream please use a special bung to remove heat..

If the engine is working with high EGT temperature (more than 800C) like the turbocharged engines.You should install the sensor at least 60cm away from the downstream and use a special bung to remove heat.

To prevent collection of liquids between this sensor housing and sensor element during the cold start phase, the installation angle should be inclined at least 10 towards horizontal with the electrical connection upwards..
